RAILROAD-SPIKE AND LOCK.

To all whom it may (20mm; v I

Be it known that I, GEORGE F. A. OOHS, a citizen of the United States of America, residing at Newark, in the county of Essex and State of New Jersey, have invented new and useful Improvements in Railroad- Spikes and Locks, of which the following is a specification.

The object of the invention is to provide a railroad spike, particularly adapted for use in connection with composite ties wherein metal marginal plates are used in connection with a filler of fibrous material, whereby the displacement or the loosening of the spikes due to the jarring or vibration incident to travel over the rails will be prevented, and yet wherein the removal of the spikes to permit of replacing or repairing the rails or ties is facilitated, and the spike is adapted for use in connection with the rails at switches as well as on the main line, and with this object in view the invention consists in a construction and combination of parts of which a preferred embodiment is shown in the drawing, wherein:

Figure 1 is a perspective view of a composite tie provided with seats for the re ception of the improved spike.

Fig. 2 is a transverse section on the plane indicated by the line 22 of Fig. 1 showing a spike in operative position in the tie and in engagement with a rail supported thereby.

Fig. 3 is a detail View of the spike.

Fig. 4 is a similar view of one of the looking dogs.

The tie in connection with which the spike is preferably used is of the composite type consisting of the top and bottom plates 10 and 11 between which in layers or otherwise is arranged a fibrous filler 12 preferably paper layers treated with creosote held in place by transverse rivets 13 or the equivalents thereof, the top plate being provided with spike seats 1% in proper positions for the reception of spikes 15 designed to secure in proper position upon the tie a track rail 16 of any conventional or preferred form, the head 17 of the spike being adapted to overlap the foot or base 18 of the rail in the ordinary way.

The seats 14: are preferably extended only through the top marginal plate of the tie to the end that the spike inserted therein may be driven into the fibrous filler and in or der to secure a proper engagement of the Specification of Letters Patent.

shank with the filler the former may be-provlded at and near its penetrating end with serrations 19 having abrupt upper shoule.

ders20 to resist withdrawal of the spike and thus serve to interfere with the upward displacement thereof.

Asa further means,however, of insuring the proper engagement of the spike with the tie it is provided with one or more lateral shoulders 21 arranged near the plane of the head l7 and adapted to pass through thetop marginal plate 10 of the tie for engagement by one or more dogs 22 mounted in suitable cavities adjacent to the under surface of'the plate 10 and yieldingly held in position to engage the shoulders by means of springs 23. Said dogs are preferably provided with stems 24 upon which the springs are fitted when the latter are of the coiled type indicated in the drawing, while projecting.

upwardly from the body portions of the dogs and extending through guide slots 25 in the top plate are studs 26 which being accessible from the under surface of the tie may be actuated to disengage the dogs from the shoulders of the spike when it is necessary to withdraw the latter for the purpose of repairing or replacing a rail or tie or otherwise repairing the road bed.

The shank 27 of the spike below the plane of the shoulders 21 is beveled to repress the yielding dogs as the spike is driven to place with its head in engagement with the base or foot of the rail, it being obvious that the dogs will spring into engaging relation with said-shoulders as soon as the spike reaches -its proper position, while above the plane of said shoulders 21 the neck 28 of the spike is preferably rectangular in form with its surfaces parallel with thelength of the spike.

It will be understood moreover that whereas the illustrated spike is provided with a shoulder 21 at each side, and oppositely located dogs are mounted in the tiefor engagement respectively with said shoulders,

the duplication of these features serves merely as an additlonal securlty masmuch as the engagement of a slngle shoulder by a corresponding dog will under normal condiactuated dog housed in the tie beneath the said plate for engagement with the shoulder when the spike is in its operative position.

2. A railway tie of the composite type having a top plate provided with a spike opening and a fibrous filler, of a spike having its shank provided with a lateral shoulder, and a spring-actuated dog mounted in a cavity in the tie adjacent to the marginal plate and provided with an upstanding stud operating in a slot in said plate for facilitating the retraction of the dog to release the spike.

3. The combination with a composite tie having a top plate and a fibrous filler, and yielding locking dogs in operative relation with a spike seat in said plate, of a spike provided with terminal serrations and having at an intermediate point in its shank lateral shoulders for engagement by said dogs, the portion of the shank extending downwardly from said shoulders being beveled for repressing the dogs as the spike is driven into the tie.

In testimony whereof I affix my signature.
